BARGE-UNLQADING MECHANISM.

Application filed June 8,

To all whom it many concern:

Be it known that 1, LELAND Rosnunn, a citizen of the United States, and resident oi the city and county ot' San Francisco, State of California, have invented new and useful Improvements in Barge-Unloading Mechanism, of which the following is a specification.

My invention. has for its object the com bination of a barge and unloading device whereby a load carried by the barge may be readily transferred by a series of unit loads from the barge to an adjacent ship, whart or other structure, and is particularly up plicable to the coaling of ships from said barge. The combination of barge and transfer mechanism comprising my invention consists of a locomotive crane including a turn table and grab bucket, adapted to travel on tracks mounted longitudinally of said barge, together with a hopper mounted idships into which the bucket is adapted to be discharged; and a skip or elevating device which receives the load from the hopvertically and which skip is adapted to travel in suitable ways to discharge chute which is vertically adjustable and is adapted to receive the load from the bucket and transfer the same by gravity clear of the barge.

Reference is herein made to mycopending applications Serial No. 331,085, filed Got. :16, 1919; No. 344,259, fil d Dec. 11, 1919, and Ser. No. 175,909 filed June 8, 1921.

Uther objects will appear from the drawings and specifications which follow.

Figure 1 is a plan view 01? a barge equipped with my unloading apparatus.

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 is a cross sectionot Fig. 2 on the line TIL-H thereof Fig. 4 is a detail of the track and track supports for the locomotive crane.

Throughout the figures similar numerals refer to identical parts.

The barge is shown by the numeral 1 which is provided with the bunker space as at 2, 3, 4;, 5, 6, 7. Mounted amidships is the gallows frame 8, 9, within which are mounted ways 10, 11, within which the skip 12 is vertically movable by the rope 13 and winding engine and drum 14. At 15 is a discharge hopper into which the said skip is adapted to discharge its load when it is raised to any elevation at which the hopper 15 may be adjusted. The discharge hopper 1921.

may be raised or lowered to any position wi hin the gallows frame by the rope 16 and winding engine and drum 1?. Power :tor the drums 1 1, 17, may be derived from the boiler 18, or electrically, or other power maybe employed in well known ways. At 20 is shown the grab bucket suspended from the boom 21 and adapted to be raised and lowered or swung side ways into any rcquired position, or the boom moved up or down as required, all by the power means 22 derived from the boiler 23, or the said power may be applied electrically or in any other well known way, whereby the bucket may be caused to be raised from or lowered into any of the bunker spaces 2, 3, 4i, 5, 6, 7, or transported into a position as over the hopper 25, as shown in Fig. 2, when the bucket may be opened by the engineer who con trols the power means at 22, and its load then emptied into the said hopper. From the hopper the load travelsfby gravity on the sloping bottom 26 into the skip 12 and the skip is then raised by the rope 13 and power means 1 1 until the skip engages the discharge hopper 15, when the load of the skip is emptied into the hopper and is caused to travel downward by gravity on the sloping bottom of said hopper until it discharges in the direction of the arrow 27 01' Fig. 3.

It will now be seen that coal may be abstracted. from any of the bunker spaces 2, 3, 4, 5, 6, 7, and discharged through the discharge hopper 15 in the direction of the arrow 27 of Fig. 3, and at any required elevation. The details of the discharge hopper 15 and of the skip 12 and means and manner of weighing the coal in transit are set forth more fully in my copending applications, and especially Serial No. 331,085, filed October 16, 1919. It will also is seen that the grab bucket may be employed for transferring a load from any position within the dotted line 30 into or cit of the barge. The said. line 30 being the range of bucket movement.

Within the hull 1 is a suitable floor 81 and sloping sides 82, 33, which form the bunker space 2 to 7 inclusive (see Fig. 3). The boom 21, from which the bucket 20 is suspended, is pivoted at 3 1 on the transfer carriage 35,.which carriage is provided with suitable wheels 36 adapted to travel on the tracks 37 38, longitudinally throughout the length of the bunker space, and by the aforesaid pivotal relation the boom may be swung about the carriage 35 over any portion of the path 30. 30, of Fig. 1. In this way it will'be seen that the bucket may be employed to handle material from any position within the path 30; that is which is the range or" the grab bucket movement and to transfer said load either on or off of my barge. Also by mounting tracks over the bunker pace the grab bucket 20 may be moved into position over any'of the bunker space and employed to lift a load therefrom and deposit the same in any portion of the path 30 or within the hopper '25 from which it may be raised by the skip l2 and transferred through the discharge hopper 15 in the direction of the arrow 27. It is to be noted that in the barge of m )resent U .1 l

invention the apparatus may be employed for loading the bunker space on the barge from a Wharf, or adjacent lighter, and the barge may then be shifted and the apparatus again used for unloading said barge load into a ships bunker.

I claim:

1. In combination with a barge, mechanism for transferring a. load comprising tracks longitudinally disposed over bunker space in said barge, a transfer carriage adapted to travel on said tracks, a grab bucket and means supporting same and adapted to raise or lower and to laterally move said bucket, said means supported from said carriage, whereby the bucket is given field of travel over the bunker space, said means comprising a boom pivotallv mounted on the transfer carriage, and power actuated devices for moving said bucket and said boom and said carriage, and a skip and substantially vertical ways having clearance therein for the passage of said carriage, said boom and said bucket positioned amulships, a hopper positioned to receive a load dropped from said bucket and to transfer the same into the said skip, a discharge chute into which the ship is adapted to empty its load.

2. A barge and apparatus as set iorth in claim 1. wherein said chute is adjustable vertically and extends laterally downward and clear of the barge sides.

3. A barge and apparatus as set forth in claim 1, wherein said boom is constructed and adapted to swing said bucket beyond the sides of said barge.

4-. A barge and apparatus as set lorlh in claim 1, wherein said boom is constructed and adapted to swing said bucket over said bunkers and also over a range beyond the sides of the barge.
